MOLD FIOR PLASTlC SHINGLESw.

SPECIFICATION forming part of Letters Patent No. 746,771, dated December15, 1903. Applicationlled September 16,1903, Serial No. 173.382. '-NcModeln vTo all whom it may concern:

Beit known that We,` NOAH D. ACKLES and EDWARDYR. KooNrz, citizens ofthe United States, residing at Plymouth, in the county of Marshall andState of Indiana, have invented certain new and useful Improvements inMolds for Plastic Shingles; and we do hereby declare that the followingis a full, clear, and exact description of the same, reference being hadto the annexed drawings, making a part of this speciication, and to theletters of reference marked thereon.

The present invention has for its object to provide a mold that will beespecially adapted for the manufacture of plastic shingles composed ofcement, concrete, and like composition, whereby a shingle is produced totake the place of the ordinary slate shingle and will possess increasedstrength anddurability; and it consists in a mold constructedsubstantially as shown in the drawings and herein described and claimed.

Figure l of the drawings is a perspective View of a mold embodying ourinvention; Fig.

2, a central cross-section thereof; Fig. 3, aY

detail perspective view showing a portion of one of the end sections ofthe mold and aportion of the removable division-plates; Fig. 4, aperspective view of the plastic shingle complete after it has come fromthe mold.

In the accompanying drawings, A B represent the side sections of themold, and C D the end sections thereof, which are separably connectedtogether, said sections-being constructed of wood or any other suitablemate- Y rial. The side sections may be of any suitable length and Widthand are provided upon their outer sides with metal braces aand elongatedholes or openings h to receive the projecting ends of metal bars E,which are connected to the outer sides of the end sections, these barsalso forming braces or stays to said end sections. The side sections arerabbeted upon their inner sides near their ends to form shoulders c,against which abut the end sections, and the projecting ends of the barshave slots d to receive suitable tapering keys e to hold the side andend sections togetherv .and enabling the sections to be separated SUwhen desired. The end sections C D have a plurality of upright orvertical kerfs or grooves f upon their inner sides to receive the endsof vertical partition-plaies F,Which 'may be` of metal or other suitablematerial,

and are each provided upon one of their sides and near one end with twopins g, which formV the nail-holes in the completed shingle. It shouldbe understood that the projecting pins g on one partition-plaie areentirely independent of the pins on the plate next to it, eachpartition-plate having its pair of'pins at one end and upon one sideonly, and said pins are a fixture to the plate by being integral`therewith or rigidly connected thereto and form a part of said plate,and when the plates are withdrawn the pins come with it. It willtherefore be seen that the pins perform a double function in that thepins serve to form the nail-holes in the shingle when completed; butalso act as supports for the shingle to hold it in contact with thepartition-plates, so that when the plates are removed the shingles willbe removed with said plates, this being a feature of material importancein the manufacture of plastic shingles. It will be noticed that thekerfs or grooves are so arranged with relation to each other that thespace between the partition-plates will be slightly tapering, so thatthe plastic shingle when removed therefrom Will be correspondinglytapering, as shown in Fig. 4 of the drawings.

In Figs. l and 2 of the drawings the composition from which the shingleis produced .is shown at between the partitions, and the vcompletedshingle when removed from the mold is shown atH in Fig. 4 of thedrawings.

Any suitable composition may be used in the manufacture of the shingle,but it is preferable that a cement be employed for this purpose, andwhen the side and end sections are connected Vtogether and the removablepartition-plates placedY in their proper position the cement in itssoftA plastic` state is placed between said partition-plates until thespace is well illed and packed. When the cement has set sufficiently,the keys are then removed and the end and side sections separated, andthe partition-plates removed, as are also the molded shingles, thepartitionplates, with their studs or pins, being one of theessentialfeatures of the invention, as the shingle when removed therefrom iscomplete in itself, with the perforations necessary for the nails usedin securing the shingle in place.

A suitable metal lining G, with flanges h at both top and bottom, may besuitably secured to the sides of the sections A B, and said sections, ifdesired, may have shoulders t', which, in connection with the shouldersc, will better hold the end sections in place. Itis preferred to havethe surface of the metal lining G perfectly smooth or polished toprevent the danger of the plastic material adhering thereto, and thelining may be removed for cleaning when found desirable.

Having now fully described our invention, what we claim as new, anddesire to secure by Letters Patent, is-

l. A mold for plastic shingles, a plurality of partition-platesremovablyconnected thereto, each plate having upon one end and side twoprojecting pins a suitable distance apart to form the necessarynail-holes in the shingle when finished, said pins being integral withtheir respective plates so that the pins will form a support for theshingle while the plate is being removed from the mold, substantially 1arms connected to the outer sides thereof, said arms projecting beyondthe ends of the sections and extending through slots in the sidesections, and keys engaging slots in the ends of the bars to hold theside and end sections together, and a plurality of removablepartition-plates engaging the vertical grooves in the end sections, andpins upon one side and near the end of each section to form thenailholes in the shingle, substantially as and for the purposedescribed.

3. A mold for plastic shingles, comprising side and end sectionsseparably connected together, theend sections having a plurality ofvertical slots and the side sections having flanged linings upon theirinner sides and shoulders for the end sections to abut against, and aplurality of removable partition-plates adapted to engage the slots inthe end sections, land pins upon one side and near one end of theplates, substantially as and for the purpose specified.

In testimony whereof we affix our signatures in presence of twoWitnesses.
